here a code :
a=imread('1e.png');
r=imresize(a,[64 64]);
bw=im2bw(r);
[m,n]=size(bw)
m =
64
n =
64
[x,y]=meshgrid(1:n,1:m);
c = ((m+1)/2,(n+1)/2); %make center of the image to be the origin
|
Error: Expression or statement is incorrect--possibly unbalanced (, {, or [.
[theta,rho] = cart2pol(x-c,y-c);
how to fix this ? thanks

Sophia is correct. The problem is on this line:
c = ((m+1)/2,(n+1)/2); %make center of the image to be the origin
Do you want c to be a two-element array? If yes, change the line to
c = [(m+1)/2,(n+1)/2]; %make center of the image to be the origin
